What is PEEK coating?
PEEK (polyetheretherketone) is a robust, rigid thermoplastic material. Because PEEK has superior chemical resistance – as well as resistance to steam and water, it is often used in applications where performance at elevated temperatures is required.
What is PEEK in orthopedics?
Bioinert Polymers (Polyetheretherketone) Polyetheretherketone (PEEK) is a newly developed polymer with good biocompatibility characteristics. The biomechanical and biological advantages of the PEEK polymer make it a promising material for the development of composites for orthopedic implants.
What does PEEK stand for?
Polyether ether ketone
Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications.
Is PEEK thermoplastic or thermosetting?
thermoplastic
PEEK is one of the high-quality semi-crystalline engineered thermoplastic materials which has excellent range mechanical properties, dimensional stability, high melting point, wear, fatigue, creep, and chemical resistive properties.
Is Peek RoHS compliant?
Ecological – PEEK products are completely recyclable, halogen-free and comply with the European RoHS directive and REACH.
What is a PEEK implant?
Background: Polyetheretherketone (PEEK) is a synthetic material that was used initially in spine and hip surgery. It has the properties of being biocompatible, resistant to thermal and ionizing radiation, and resembles cortical bone biomechanically.
Why is PEEK good for implants?
PEEK has high stability, low density (1.32 g/cm3), insolubility, and a low elastic modulus (3–4 GPa) [16,17]. Chemical structure of polyetheretherketone. PEEK has some clinical advantages as a dental implant material compared to Ti. First, it causes fewer hypersensitive and allergic reactions.
Where is PEEK used?
PEEK is used to fabricate items for demanding applications, including bearings, piston parts, pumps, high-performance liquid chromatography columns, compressor plate valves, and electrical cable insulation.
Is PEEK amorphous or crystalline?
semi-crystalline polymer
PEEK is a semi-crystalline polymer, which means that a portion of its molecules aligns and forms crystals while the rest remains amorphous. The chemistry of PEEK, the strength of its bonds and its semi-crystalline structure is what gives PEEK all its amazing and extreme properties.
What are the medical applications of Peek?
PEEK’s considerable material properties lend it to many medical applications, including many implant applications. PEEK is a frontline option for spinal implants, trauma fixation, cardiovascular implants and in many other fields of medicine.
What is Peek-Classix™ polymer?
Medical manufacturers are seeking streamlined design, manufacturing, regulatory and supply-chain solutions that achieve more with less PEEK-CLASSIX™ polymer from Invibio is a medical grade, high performance, biocompatible polymer suitable for applications requiring blood or tissue contact of less than 30 days.
What is the difference between Peek and metal in plastic surgery?
PEEK is much lighter than metal, which allows patients to manipulate joints and limbs with less effort than would be necessary with heavier metals. The difference may be subtle, but patients have already reported improved comfort with PEEK components.
What is a peek tether in cardiac surgery?
During LIVE procedures, a pair of anchors are positioned over the left ventricle, which tends to suffer the most during myocardial infarction. These anchors stabilize the ventricle and ensure it maintains its functionality. The anchors are tied together using a PEEK tether, which keeps the anchors in place, relative to each other.
